Copernicus now has honeybees at the Hortus and it was time for their first inspection. They do well in the Hortus with this weather. Linden (Tilia) is blooming in the Uithof and giving a lot of nectar after the rain. The bees turn it quickly into new wax combs and honey stores.Having institute bees gives interesting research possibilities, from developping and testing measuring systems to using the bees themselves as environmental monitors.
